ACCOUNTING-MACHINE Specification of Letters Patent Pabenfiefl Ngv, 2219111 Application filed ere 26, 1909.' Serial No.280,178.

automatic manner, the envelops being automatically discharged as theyare printed upon. ment of this character is shown applied to the rearportion of a well-known type of adding and listing machine and soconnected to the working parts of such machine that as the amount keysare manipulated to set.

up different amounts and the. handle of the machine is pulled or themachine is otherwise operated in a familiar manner, envelops stackedin'a suitable runway are successively taken from the stack singly,presented with the desired portion confronting the type, held at suchposition so as to receive an impression from the type, then dischargedand finally 're-stacked.

With the aboveobject in view the invention. consists in certain novel.featurcs of construction and combinations of parts, the

essential elements whereof are recited in the appended claims and apreferred form of embodimentof whichis described in detail hereinafterand fully illustrated in the ing such as obtain at the middle ofanoperation of said machine, Whereas in Fig. 1 the various parts areshown at normal; Fig. 3 is a vertical cross section of the attach menttaken substantially on the line 3-3 of 'Fig. 2; Fig. 4 is a sectiontaken substant1a ly on. the line 44 of Fig. 3; Fig. 5.is

In the present instance an attach arts of the adding and listingmachine, t e conditions bean enlarged detail section talren on line 5-5of F 1g. 2; Figs. 6 to 10 are enlarged sections and illustratingthesuccessive steps in handling the envelops; and Figs. Hand 12 show anenvelop before andafter treatment. It will not be necessary to describein detail the adding and listin machine here shown but reference may hehad to Burroughs Patents 5%,963 and 505,078,'issued September 12, 1893.It is to be understood that this is merely chosen as one of severaltypes of adding and listing machines and that the invention is adaptableto other types. It is proposed. in the present embodiment of theinvention to apply the attach-- aper carriage is ment where ordinarily amounted. Thus a supportlng plate .9; is secured across the back of themachine, being suitably bolted or otherwise attached to the mainframework 3 of the machine. There is seouredwto this plate projectingrearwardly therefrom a box 4 here shown as of considerable depth andrectangular in cross section. The lower portion of this box 0011-,stitutes a runway for envelope stacked with ends resting on the'bot-tomof the'hox as shown in Fig. 4t. An opening 5 is provided in one side ofthe box as shown in Fig. 3

through which to introduce the envelops in packages. They can be sointroduced with the usual bands (in-them and such bands broken andremoved after the packages of envelops have been stacked in the box. Aplate 6 (Fig. i) is mounted to travel in the box as a follower for thesimilar to the right-hand portionof Fig. 4

stack of envelope, constantly thrusting the same forward. Said plate ispreferably equipped with rollers '7 to run on the bottom of the box andreduce friction. The plate has ears 8 (Fig. 4-). overlying ears 9 on ahead 10 of a lunger rod 11, and a swivel pin 12 extent through the earsand said plunger rod, connecting the follower and the plunger rod so asto allow for pivotal movement of the former to compensate i'orirregularities in the envelops and provide for close engagement betweenthe follower and the rearmost envelope and .for uniform pressure tendingto. advance the stack of envelops. The lunge'r rod 11 is here shown intheform "ol a channel bar. but may of course take various forms. Thereis secured to its rear end, which rotrudes from the box, a cable 13running orward overasheave or pulley 14 and having suspended on it aweight 15. Saidsheave or pulley is supported in a, suitable bracket 16secured to the back of the'box and it will be obvious that the weightacts to constantly thrust the follower 6 forward, forcing the envelopsto the forward end of the box as long as any of them are contained inthe box.

Mounted on the front side of the box l is an envelop lifter which is inthe form of a rectangular plate 17 confined in a vertical slidewayformed in the rear side of the supportin plate 2, the box at not havingafront side-0t its own but partially closed at the front by saidsupporting plate. The lifting plate 17 is thus presented to thefirst-envelop of the stack in the box and such envelop will be closelypressed against said lifting plate. The latter is thickened along itslower edge and formed with a ledge or shoulder a, and the bottom of thebox -lis cut out so as to provide for the thickened portion of thelifter plate passing down throughsuch bottom until said ledge orshoulder is flush with the upper surface of the bottom of the box asshown in Fig. 7. Normally, however, the lifter plate is elevated asshown in Fig. f so that said shoulder or ledge is considerably above thebottom of the box, as shown in Figs. 4, 6, 8 and 10.

In the upper forward portion of the lower division of the box whichcontains the stack of envelops there is mounted a stop bar forpreventing any but the foremost envelop rising. As here shown this barcomprises a head 18 and a shank 19, the latter bifurcated to embrace across rod 20 supported in the sides of the box. This shank contains aspring-pressed plunger 21 bearing against said cross rod, the springacting to thrust the stop bar forward. The head 18 of the latter is alsobifurcated and embraces the central portion of a shaft 22. The lowerforward corner of the head 18 is slightly chamfered onrounded off sothat the foremost envelop when lifted by the plate 17 may enter the biteof a pair of feed rollers 232 l, the latter carried by the shaft 22. Thespring applied to the plunger 21 is comparatively light so that it mayyield when the said envelop is lifted and as it is carried up by thefeed rollers. Frictional, engagement between this and the next en velopis prevented from causing such next envelop to rise, by reason of theobstruction offered by the head 18 in advance of the up er edge of suchnext envelop.

t will be later explained through what particular means motion isimparted to the ifter plate through the operation of the adding andlisting machine but it may now be stated that with the latter at normalthe lifter plate is elevated and a blank operation of the adding andlisting machine will condition is illustrated in Fig. 4.

'27 towardthe roller 28.

lower the lifter plate so that the foremost envelop will thereuponengage over the shoulder or ledge a and then said plate will rise so asto carry the foremost envelop up into the bite of the feed rollers23-2l, which At this time said feed rollers are in motion so thatthey'take hold of the envelop and at the coin clusion of the blankoperation stand ready to further raise the envelop. Fig; (3 illus tratesthe condition when jthe machine is at normal and a stack of envelops isput'into the box and the follower released'so that it is pressing thestack forward. Fig. 7 illus trates the condition shortly after thecommencement of the blank operation of the adding machine. Fig. 8illustrates the con-i dition at the conclusion of such blank operation.A in each of these figures designates the foremost'envelops.

In ensuing operations of the adding machine in which the amount keys 221(Fig. 1) are manipulated and the shaft 300 oscillated by the drawingforward and release of the usual operating handle or otherwise, theenvelops will be brought one at a time to position for receivingimpressions from the type plates 618. In the box 4: just above the stopbar 1819 there is journaled a platen roller 25 (Fig. 4) located to backup the envelop ..when the type plates 618 are drivenagainst it, it beingunderstood of course that a suitable inking ribbon intervenes. Thesupporting plate 2 is open in front of said platen roller and thereproject from the sides of the opening suitable guiding clips-26 behindwhich the envelop passes when advanced to printing'position by the feedrollers 2324-. In' line with the said feed rollers and located above theprinting line are similar feed rollers 27-28, the

latter secured to a shaft 29 journalett in the sides of the box fl.There are here shown two feed rollers 23 and two feed rollers 27 and thefeed rollers2 l and 28 are of sectional construction as shown in Fig. 3

uncovering the shafts 22 and 29 for a space at the middle of each. Thusthere are ina sense four pairs of feed rollers, two at each side. Thefeed rollers 23 are journaled in springs 33 or causing said rollers 23to be pressed yieldingly toward the roller 2- The upper rollers 27 arejournaled in arms 34: loose on a cross rod 35 supported in the sides ofthe box 1, at the upper forward part thereof. Spiral springs 36 extendbetween studs 37 on said arms 34 and the screw studs 31, said springsserving to press the rollers The arms 34 not only serve to support therollers 27 but also act to deflect the envelops as they are fed intoraised andthe foremost envelop brought be-' the upperpart of the box 4by the feed rollersas indicated in Fig. 4, said arms being inclinedrearward.

It has before been stated that normally the lifter plate 17 is elevatedand it has been further'explained how, in a blank, operation of themachine, said plate is lowered and tween the feed rollers 23 and 24: tothe posi tion shown in Fig. 8. In an ensuing operation of the addingmachine said feed rollers will be turned sufliciently to carry theenvelop up between the platen 25 and the type or to the positionillustrated in Fig. 9,the upper edge of the envelop being then in thebite of the rollers 27-28. The envelop remains at this position untilthe printing has taken place. Then during the return movement of theadding machine handle or re turn rocking of its drive shaftythe feedrollers .23 and 24- are further turned and also the feed rollers 27-28so that the envelop will be carried upward to the position shown in Fig,10 .or until its lower edge has moved beyond the printin line. Then whenanother operation of t i eadding machine starts the feed rollers 27-28again move and dis charge the envelop, another meantime being brought tothe printing position. The arms 84 deflect the envelop as it isdischarged by the rollers 27-28 so that it will fall backward withtheprinted side uppermost.-

The platen roller 25 is grooved, at each end to receive bands or belts38 which engage similar grooves of a 'pulley 39 journaled between arms40 Which at their forward ends loosely surround the platen roller shaft41. These last-described parts constitute airendless con'veyeruponwhichthe envelops fall when discharged from the upper feed rollers. The upperstretches of the conveyor belts travel rearward so that the printedenvelops are moved toward the back otthe box at. Here the box is formedwith an incline 42 up which the rearmost envelop will slide so that thelatter eventually assumes a partially upright position as shown in Fig.4, following envelopslsliding'up on each other so that the envelops willbe stacked after having been printed. The arms to are connected bysuitable cross rods 48 and normally extend horizontally resting uponpins 44 which roject from the sides of the box. The endless conveyorthus. di vides the box into upper and lower compartments but if desiredto gain'access to the lower compartment through the top of the box theconveyor can be raised swinging on the platen shaft 41. This may befound more convenient at times when introducing a large number of envelointo the runway, as compared with intr ucinga bundle at a time through"the said opening 5.

It remains to describe the means here shown for imparting movement tothe lift plate 17, the teed rollers and the roller platen. thesevariousparts takes the tormot a lever having a segmental portion 50 above itspivot (see Figs. .1 and 2) and an arm 51 below its pivot, the latterpivotally connected to a link 52 which extends through an The main.op'eratin member for i opening in the supporting plate 2 and is formedat its forward end with jaws 53. The latter embrace a wrist pin or shaft54- carried by crank arms 110' secured to a rock shaft 100. This shaftand itsarins 110 as well as the wrist pin or cross shaft 54 are allfamiliar parts of the Burroughs adding and listing machine and it willbe understood -that they oscillate in each operation of such machine.Hence with the jaws of the link 52 engaging the shaft ,or wrist pin 54,the

lever505l will be vibrated every time the machine is operated. Thislever is suitably pivoted between the side of the box 4 and a bracket 57projecting from the supporting plate ,2, and has fa forwardly-projectingprong 56 normally engaged with a stud 58 (Fig. 1) on a strip or bar 59slidably mounted upon the supporting plate-2 as shown in Fig: 3. Saidstrip or bar is there shown as formed with laterally turned endportions, the upper one of which is slotted to receive a screw 60 andthe lower one of which is connected by a screw stud 61 witha lever 62mounted on the front side of the plate 2,

said screw stud extending through a slot in 17, said studs 63 working ina vertical slot of-t'he plate 2 (Figs. and t). I

As the handleot the adding machine is pulled forward it will be obviousthat the accompanying rearward swing of the crank forward movement ofthe operating handle.

There is formed in the segmental upper. portion 50 of the driving leveran oblique slot 70 the sides of which act with a camin'ing efiect upon aroller on the end of one arm ofa' bell crank lever 71 pivoted on a studprojecting from the side of the box 4 and carrying pivoted to its otherarm an elongated pawl 72. The latter is adapted to act upon pins 73yrojecting from the side of a gear wheel 74. the latter journaled upon astud 75 which is secured to the side of the box a .(see Fig. 5). Aspiral spring 76 congear wheel is further rotating.

It will be seen that rocking of the lever 51 caused by pulling theoperating handle of the adding machine forward will rock the'bell crank71 in a direction to advance the pawl 72. Normally the acting edge orshoulder of the pawl stands a little in rear of one-of the pins 73.Consequently as the operating handle starts the pawl moves up to saidpin and in continued forward movement of the handle acts upon said pinto turn the gear wheel 74.. The latter is in mesh with pinions 78 and 79on the feed roller shafts 22 and 29 so that-this movement of said gearwheel causes turning of the feed rollers in a direction to carry theenvelop upward. The measure of this movement is such as to take theenvelop to the printing position illustrated in Fig. 9. Here the upperfeed rollers 27 and 28 do not act upon the envelop but the lower feedrollers 23 and 2 alone perform this function, carrying the upper edge ofthe envelop into the bite of the upper feed rollers. It will beunderstood that this assumes a blank operation of the machine to havepreviously been made with the result before explained, to-wit, that oflifting the foremost envelop of the stack into the bite of the lowerfeed rollers, the latter having taken hold of the envelop as illustratedin Figs. 6, 7 and 8. Of course in such blank operation the upper feedrollers are performing no work.

It will be understood that at the conclusion of the forward movement ofthe operating handle rinting takes place, amount keys 221 having beendepressed before the handle is pulled. There is a short dwell at thelower end of the cam slot 70 which provides for the gear wheelsremaining stationary and the envelop consequently being immovable duringthe printing.

A gear segment 80 is formed upon the upper portion 50 of the drivinglever and this gear segment is in mesh with a pinion 81 journaled uponthe stud (Fig. andsecured to a ratchet wheel 82 mounted alongside of it.A pawl 83 is pivotally mounted on the side of the gear wheel 74 andspring-pressed into engagement withsaid ratchet wheel (Figs. 1 and 2).During the rocking of the driving lever already described the pinion andratchet wheel are turned in the direction of the arrow in Fig. 1 so thatthe teeth of the ratchet wheel simply click ast the pawl. Upon thereverse rocking of the driving lever, however, which accompanies thebackward swing of the operating handle, said ratchet wheel drives thegear wheel 74: through the medium of the pawl 83. This turning of thegear wheel rotates the feed rollers so as to carry the printed envelopup to the position shown in Fig. 10, the lower feed rollers first actingin conjunction with the upper feed rollers to pass the envelop along andthe upper feed rollers then acting to carry the envelop beyond theprinting position. Meantime the prong 56 rises and acting upon the stud58 elevates the lift plate 17, raising the next envelop into the bite ofthe lower feed rollers and the rotation of the latter having continuedthey take hold of this envelop, moving it to the position shown in F ig.8. To prevent overthrow when the gear segment comes to the end of itsreturn movement after driving the gears in the manner described, thereis loosely mounted upon the same stud which supports the bellcrank 71, apawl 85 which is swun spiral spring 86 (Fig. 2) but moved against thestress of said spring by contact of the driving lever with a stud 86 onthe arm of said pawl which depends from its pivot (Fig. 1). This rockingof the pawl by the driving lever engages its notched end with one of thepins 73 of the gear wheel 74:-

which obviously prevents any overthrow of the latter. The lost motionbetween the pawl 72 and the pins 73 on which it rests provides for theunlocking of the gear wheel before said pawl acts upon said pins.

in the next ensuing operation while the lower feed rollers areadvancing'the next envelop to the printing position the upper feedrollers discharge the printed envelop, the latter being deflected by thearms 34 and falling backward onto the conveyer. As one operation afteranother takes place the printed envelops thus discharged upon theconveyer are carried rearward by the same and eventually the firstenvelop strikes the boxincline as, (Fig. 4). The envelops will lie oneupon another at different inclines as the operations proceed so thatthey are stacked in the upper compartment of the box in regular order.

Means are provided for turning the roller platen step by step for thepurpose of intermittently actuating the conveyer and also for thepurpose of distributing the wear .on the .platen. Thus there is securedto the right-hand end of the platen journal a ratchet wheel 90 (Figs. 1and 2) which is engaged by a tooth 91.0n an arm 92 pivoted intermediateits ends to a crank arm '93 which is rigid with thedriving lever. Aspiral spring 94 connects the lower end of said arm 92 with a stud onthe side of the box 4, said spring holding the tooth 91 in engagementwith the ratchet wheel. The latter has an odd number of teethtwenty-onein the present insta'nceand the tooth 91 Or rearwardly by a erases has athrow of an even number of teeth,

in the present instance 4. It will be chduring the further movement ofthe operating handle but comes to a close just as the hammers of theadding machine are fired.

It will be'obvious' that the intermittent turning of the platen rollermoves the conveyer belts in a direction to carry the printedv enveloperearward. I

It is suflicient for the upper pressure rollera 27 to simply bear uponthe companion rollerv sections 28 but as the lower set of "feed rollershave more work to do in extract ing the front envelop from thestackagainst the friction between it and the next envelop,

it is preferable to gear the slower feed rollers together. To this endthe shaftQQ carries small gear Wheels95-96 which mesh respec tivelywithsimilar gear Wheels 97, 98 on the pressure rollers 23 sothat the latterare respectively driven .and do not rely simply upon friction engagementwith the envelop to receive rotary movement. 4

A machine equi ped as above described will be found use ulinmany'connections, but it will suliice to refer specifically to one,to-wit, its use in a paymasters office. In

this connection the attachmentmay be assinned fo'r'example'tobe on amachine such as that shown in Vincent Patent No. 908,430, issuedDecember 29, 1908, where provision is i made for splitting orsubdividing the printing mechanism, and extending the total to theadding Wheels associated with the lefthand section or subdivision.-Envelops will r be stacked in the lower 'compartment of the box 4 withthe sides to be printed '(Fig. 11)
